' 2 Claims. (01. 85-5) My invention aims to provide improvements in asshown in Figs. -6 and 7, to allow for expansion strip-attachingfastening members and installaof the side walls l3-I3. The bottomportion of tions thereof. the attaching portion i is pressed inwardly toIn the drawing which illustrates a preferred provide a fold H extendingtoward the base porembodiment of my invention: tion 9, as clearly shownin Fig. 5. The strip- 5 Figure 1 is a more or less schematic view of agripping portion H is preferably in the form of portion of a doorstructure showing one of my a hook extending from one edge of the baseporimproved fastening members holding a strip in tion 9 (Fig. '7) andhaving teeth I5 at the free position; endof the hook, as shown in Figs.5 and 8.

In the present daymotor vehicles rubber just described the strip 3 is securely attached inor other similar material in flexible strips is used the desiredposition around the door by manipubetween the door and thedoor-supporting frame lating the strip relative to the hook portion of a30 to seal the space against either the inflow or out fastener so thatthe hook portionenters into the flow of air. It should be understood,however, slot 5 in the strip 3.

This tool (not shown) and fastener Ihave selected for illustration of may be manipulated in any suitablemanner to my invention by the annexed drawing, I have cause thehook-shaped portion to be clamped into shown th diagrammatically(Figure 1) a, porengagement with the attaching portion 1 of the tion ofa door I, a portion of a door support 2, strip 3 (Fig. 2).

It will benoted that the ga n p n M y b changed fr m the pe strip 3 is of specialshapein cross-section and has shown in Fig. '7 to the shape shown inFig. 2 a groove 5 dividing the strip into a clamping porand the teeth Itare embedded in the material tion I and a free flexible sealing portion8, as of the strip 3 to prevent it from slipping when the 45 clearlyshown in Fig. 2. strip is pulled tightly duringthe positioning oper Myimproved fastening device (Figs. 5, 6, '7 ation. and 8) is preferablyformed from a single piece My improved fastening device is particularlyof soft bendable metal such, for instance, as cold useful in connectionwith the type of installation rolled steel. The fastener has a baseportion 9, described because the expansible attaching por- 50 anexpansible attaching portion I0 and a hooktion In adapts itself readilyto substantial tolershaped strip-gripping portion II. The attachances inthe aperture l6 and also in the thicking portion is preferably pressedfrom the base ness of the part through which it passes. Furportion 9 andhas' two of its opposed side faces thermore, once the fastener issecured in position |2-I2 free from the base portion and cut away,itcannot be pulled loose through any normal or 55 even substantialabnormal stresses exerted upon it. Furthermore, since the attachingportion. is required to be of material which may be easily bent itpermits the strip-H199 portion i I being made as an integral part of thefastener and of soft material so that it also may be deformed to astrip-gripping shape thereby secureiyholding a suitable strip.

My improved fastener and installation are understood that changes in thefastener and uses.

thereof with other forms of parts than thosespecifically described maybe made without departing from the scope of my invention which is bestdefined by the following claims.

I claim:

1. A fastening device of the class described formed from one piece ofsheet metal and having a base portion, an attaching means extending fromsaid base portion at one side thereof and a clamping portion integralwith said base portion,

said clamping portion having a portion extending away from said base inangular relation thereto and a free end portion extending toward saidbase, said free end portion having a sub-'* stantial width and providinga row of teeth at its outermost-freei endi 'so "as-to engage a. stripdisposed betweensaid freeendand said base for clamping said strip tosaid base;

.2. A fastening device of the class described formed from one piece ofsheet metal and having a base portion, an attaching means extending fromsaid base portion at one side thereof and a clamping portion .integralwith said base portioh? said clamping portion having -a portionextending away from said base in --substantially right-angular relationthereto and a free end portion extending toward said base, said free endportion having a substantial width and providing a row of teeth, saidteeth being disposed substantially in the plane of saidfree end portionso as to engage a strip disposed between said free end and said base forclamping said strip to said base.
